Google's Gemini 3 / Nano Banana Pro AI Image Creation
Just playing around with free online AI image creation tools. Six months to a year ago, they couldn't handle text requests very well, but now they're nailing it on the first try with no typos or errors.

VOIP Switch from 'Hamshack Hotline' to 'Hams Over IP'
At the end of August 2025, the longtime Amateur Radio VOIP phone system Hamshack Hotline was retired. Many hams, including myself, migrated to another platform called Hams Over IP. I enjoyed Hamshack Hotline a lot, so my hopes are that Hams Over IP is as good or better.
I completed the registration step yesterday, which only took a few hours to get my extension and password from the admins. Last night I tried following the provided instructions, but it was late and I was tired, so I didn't have success provisioning my Cisco SPA-514G compatible SIP handset.
This morning, with a fresh cup of tea and a clear head, it was less than 10 minutes, and I was online. Remember to never work tired or with a muddy head.
Being able to do all the configuration via the phone's built-in web server was so nice. Just a web browser on my PC was all I needed for the work.

My Amateur Radio Mode ID's section of the blog has been updated to remove the Hamshack Hotline entry and replace it with Hams Over IP.
At the time of this post (2025-09-05), there are 8 amateurs in the Okanagan Valley with extensions on HOIP. Hoping this will grow as others migrate onto this service.
HOIP Service Test Phone NumbersAfter configuring your phone, you will no doubt want to test the connection and not have to bother anyone by calling them to see if it works ("Can you hear me now?").
Below is a list of extensions that you can call for various tests.

HF 20m Dipole Antenna Project
Goal
Building a new monoband antenna which I'll orient in the opposite direction (east-to-west) to my other multi-band 80m Off Center Fed (OCF) Dipole that's installed in a north-to-south orientation on my property.
Height will once again be a challenge as I just don't have the trees or towers required to reach an optimal height for a 20m dipole of 42 feet. Instead, I'll have to live with 25 feet as that's the max height of the trees, ropes, and pulley's that I put up last year. The good news is trees grow, but I suspect I don't have the patience for them to reach 42 feet as part of their natural growth.
What happens when a dipole is installed lower than the spec, it's radiation pattern angles higher towards the sky, this affects the range of the antenna since the signal transmitted will point more upward than towards the horizon. But my other off-center fed dipole is also lower than I'd like and I get plenty of decent contacts from that antenna, so I'm ok with the compromise.
Ingredients
- Laundry line cable with clear plastic coating (salvaged from antenna project)
- Kenpro KA-50 1:1 balun (full specs below, also salvaged from another old antenna)
- 50' RG-8 coax cable with the UHF PL-259 connectors
- (2x) black plastic insulators
- (4x) wire cable clamps
- (2x) ring terminal connectors
- Silicone rubber weatherproofing tape
- Electrical tape
Specifications
Kenpro KA-50 (1:1 Balun) Freq Range : 1.8MHz-50MHz
Impedance: 50 ohm
Max power: 1kw CW - 2kw PEP (High Power Balun)
Ratio impedance: 1:1
The measurements below are for building a simple Dipole Antenna. The Wire Size can range from 16 AWG to 12 AWG. The larger the wire, the wider the bandwidth. The antenna is designed to be fed with 50 Ohm coax cable of almost any length with a Balun.
Place a 1:1 Balun on the antenna end of the Feedline. The Balun matches the Balanced Antenna into the Unbalanced Coax Cable. The balun will keep stray antenna currents off of the Feedline and help to keep stray RF out of the Radio Shack. If a Ferrite Balun is used, the balun needs to be rated at least twice the operating wattage to prevent the balun from overheating. This will help mitigate mismatches and stray RF due to using the antenna at frequencies other than what the antenna was specifically designed for.
Frequency: 14.175 MHz
Total Antenna Length ("L"): 33 Feet, 0.2 Inches
Element Length ("E"): 16 Feet, 6.1 Inches
Correct or incorrect I added 6 inches of extra cable at each end and marked the 16'1" measurements with a sharpie on the cable clear coating.
I soldered the ring terminal connectors to one end of each cable.
Then using 1 cable clamp for each cable I secured the cables to the KA-50 balun so the weight of the entire antenna and coax is not hanging from the ring terminals. As you can see in the photo below the clamps are close to the balun and an evened length loop connects to the screw terminals on the balun.

New Silver Star Weather RADAR Station

MMDVM Pi-Star Hotspot - Quick Replacement of the SD Card (Repair Notes)
Yesterday I decided to entirely rebuild the unit's SD card using the following process. These notes are as much for me if I need to repeat the process again in the future.
Failure of SD cards is very common after continued use, especially in devices like this that run 24/7. The entire card might not fail, but sectors on the card can easily fail.
Steps
- Rebooted the hotspot and got access to the web interface temporarily.
- Took a current backup of my settings and downloaded/saved the file on my laptop.
- Note, this method requires Wi-Fi so a laptop or desktop with Wi-Fi capability is required.
- Slow formatted a replacement SD card to verify that all sectors are good.
- Downloaded the latest Pi-Star image from Pi-Star Downloads - pistar.uk
- Flashed the new image to the new SD card using the Raspberry Pi Imager app Raspberry Pi OS – Raspberry Pi
- Power down the MMDVM hotspot, full out the old SD card and replace with the new SD card
- Boot the MMDVM hotspot off the new SD card, leaving LOTS of time for initial boot steps to occur and the setup Wi-Fi access point to load (SSID = Pi-Star-Setup)
- Connect the laptop to the new temp SSID and load the start-up pages for Pi-Star
- Go straight to Configuration > Backup/Restore
- Load the backup file from step 2 and upload the file and Restore.
- Go back to Configuration and change the Wi-Fi settings to the stored settings from your home network (settings were stored in the backup and just need to be selected and applied.
- Reboot the MMDVM hotspot and everything should come up just like before the new card was installed.

“Any radio amateur currently transmitting from Ukraine is risking his or her life. If you hear a Ukrainian station, do not broadcast its callsign, location or frequency — whether on the band, in a cluster or on social media. You may be putting lives at risk.”

Drake UL68 Communications Headphones
Copied from https://www.universal-radio.com/used/sold688.html
The Drake Headphones are monaural and terminate to a 1/4 inch phone plug. There is nothing particularly noteworthy about these headphones other than the Drake logo on the left earpiece and right earpiece. Not stellar headphones, but a rare find for the Drake collector. [06/14]
I really enjoyed this short description/review. I guess I'll need to test them out for myself.
If anyone has any more technical information on these that would be greatly appreciated. I collect headphones and headsets for various purposes including Audiophile, Gaming, and Radio Communications.
With a mono 1/4 inch phone plug these are squarely in the Communications category, with Drake being an old amateur radio brand still popular with collectors.
Took me some time on the web to even find an actual model number (UL68), and it didn't help that a popular modern Canadian recording artist (Drake) dominated the search results about what headphones he personally uses when in the studio recording. Also strange that Beats by Dr. Dre also dominated the Drake Headphone searches since Drake the artist never sponsored any Beats headphones that I'm aware of?
Anyhow, another set of 'cans' for the wall.

North Okanagan Wildfire Scanner Feeds
Are you interested in monitoring the BC Forest Fire Service in the North Okanagan area, feel free to use these streaming links which do not require any radio equipment or the sharing of special or private frequencies.
The use of streaming links assures that radio interference does not occur from the general public monitoring. When using actual radio equipment the operator could improperly transmit on these critical channels if the radio is improperly programmed or the user is improperly trained on its use.
Streaming links also offer excellent audio quality as the radio receivers being used are located where the signal is strong and clear.
